Gravity is a spell in Final Fantasy XI available only to Red Mages and characters with the Support Job of Red Mage. Gravity has two effects, the first of which is to decrease the land speed of the enemy it is cast upon. It will also lower the target's Evasion, making it significantly easier to hit with physical melee and ranged attacks. This spell inflicts the status effect known as Weight.

Gravity is a Black Magic spell aligned with the Wind element. It casts off of the Enfeebling Magic trait.
